The object of this invention isvto provideV means for detecting the destructive and scale depositing properties of water or steam, by permitting action of the fluid on a special element o? metal inserted into a steam duct, main, or water container, in the special Inanner herein disclosed, the detecting device being adapted for withdrawal for examination rewarding the abovementioned properties oi the Huid and for the purpose of determining the nature of deposits when sure ris maintained, and without permittingv of the escape of fluid.

With the foregoing and other objects in view, the invention consists in the novel construction and arrangement of element-sdescribed, illustrated and claimed, it being `understood that modifications may be made within the scope of theclaimswithout vdeparting from the spirit of the invention.

In my co-p'ending application filed June 15, 1927, Serial Number 199,048, I have yshown yand described means for mounting 59 a scale and corrosion detector, and in the section through presentY case a ortion'of the construction corresponds witi that already disclosed but' the detecting element per se is mounted'by means of a connecting device dierently tormed,fand the novelty resides chiefly in the particularv detecting devices employed in the element for directly Vmounting the devices,'and. in one. form the novelty pertains to the screen construction referred to more in detail below. i y,

A feed line or'rsteam main is designated 10, andk a nipplek 11 is threaded into an open'- ing in they line, and is also threaded into the housingor rcasing ot' valveV 12. This housing has' threaded connection with nipple 13, and a pipe" union or coupling 14 connected with nipple 13 also has connection with tubul larY element 15 providing a'chamb'e'r therein as shown at 16. f e

The tubular elementl has an inner portion providinga reducedbore, this part he'- ing designated 17, and thebore being shown at 18, permitting of the l'free passage therethrough of vrod 19. The cap '20 is threaded Y intothe end of tubular' member 15, and is provided' with a central bore 21 for. the tree passage'therethrough of `rod 19. This element llast-named isv controlledy by a hand wheel 22 retained in position by a threaded element 23 having a cutaway portion orf channel 24 therein, for the"reception ot a bail-like membery 25 which, may', also'y ble termed a yoke Lor U-'me'mberfThep element 25 has inwardly turned ends'26 adapted for reception'within the openings 27 in opposite f sidesofthe cap 20, and ,theelement 25 when in operative. position retains rod 19 an inner position, Jfor thepurpose indicated below. Apacking box is designated 28 and v ,serves an obviouspurpose. i

vThe detector vor detector'rod is designated 30, andis mounted ina two-part coupling 32, comprising aplurality of sections meet-V ing in a plane through which the longitudinal axis of the device 80fpasses,'the rod* y19 being in aligmnent with element 30.

, Each ofthese elements 30 and 19 is provided with reduced` portion 33, whereby'a plurality of vannularfshou'lders arel producr-xcl,V vthese shoulders engaging a'reduced portionl of a socketformed in each end of theelement 32. vkIt will be observed that each of `the sections of the 'device 32 contains a grooved orchanneled portion, and that oppositely located channeled portions form the complete vsocket 'at each end. `The sections f of themountingdevice thus produced yare held Vtogether means of ascrew orother securing device designated 35, the head bef riQing,countersunkfas shown atV 36,*1The ele'` j V` mentl32` is ofinsulating material, so that no galvanicfactionflwill be set up between the elements y30jand 32, as might otherwise kbe the case.

The.detectingjelement 3will' be ofizinc,

`brass containing zinc, for aluminum, other f `metals orv alloysjbeing employed if desired but the investigator will selecta metal subject to partialidestruction, with deposit thereon jofxrtlie, impurities which it is believed maybe found to exist in the fluid, or held insuspension thereby. l
